ONTOLOGY-BASED WEB SERVICES SYSTEM DEVELOPMENT

Summary/Abstract: Web services systems are often created from scratch despite of already existing systems with similar functions. Therefore the same mistakes can arise in development of the systems, for example: important concepts of data model are not defined, incorrect rules model are created. Ontology is proposed to use in the development of information system for getting domain knowledge. The ways of using ontology in the development of web services systems are analyzed in the paper. The aim of this research is to improve the process of web services system development. The analysis of web services, ontology and business rules shows that it is advisable to use ontology to create set of business rules, conceptual data model.We propose to classify the rules of web services systems in order to better understand them and choose better ontology for their elicitation. In the paper ontology approach is applied for web services systems. It is proposed to use domain ontology for elicitation of domain, access, usage and orchestration rules, web services ontology can help to elicit choreography and orchestration rules.Suggested approach is examined developing prototype of university e. publication web services system. Suggested classification of web services systems rules enables easier to elicit rules and allows choosing suitable source of rules (web service ontology or domain ontology). It is found that using ontology in development process of web services systems allows creating more correct set of rules and conceptual data model.
